To all whom it may concern Be it known that 1, JOHN 'W. Hoosnn, a

V citizen and resident of Dallas, county of Dallas, State of Texas, and United States of America, have invented certain new and useful Improvements in Carbureting .Sys-

-' tems for Internal-Combustion Engines;

This invention relates to a new and useful form of carbureter adaptable for use on internal combustion motors and 1s conceived and designed for vaporizing fuel oils of the heaviervand non-volatile class for combusvtion'in the engine.

" A further purpose of the invention is to provide a carbureting system for automobile engines which will produce a resulting gas of such a quality as will give perfect com- -The' carbureting device constituting this invention, an example of which is disclosed in. this Letters Patent, particularly apper tains to a thermal carbureting systemfor vaporizing, through the agency of heat fromthe running motor, oils of low specific grav- 'ity such as that grade of oil which is known and sold in the market as coal oil. The thermal carbureter included in this invention provides means for mixing with the coal oil vapor a light steam vapor, which water va por or steam is passedto and thoroughly intermixed with a combustible vaporized mixture prior to combustionflin the cylinder 'of the engine. This provision of the vapor used in connection with the'hydrocarbon oil vapor softens 'and tones down the combustible mixture to a degree which is most efficient and thoroughly combustible i-n explo-" sion chamber at the point; of highest ,com-

pression, for the reason that the'explosive mixture. combined with the humid water vapor cuts and dlsintegrates the carbon.

which would otherwise form at thepoint of combustion within the cylinder and cause the explosion chamber and all parts associated therewith, including the spark plug a of the engine, to be thoroughly cleaned and scoured atthe point of pressure of the powerimpulse delivered by the,.comparatively quick and cleansing explosion of the said mixture.

With the above and other objects in view the invention has relation to a certain combmation and arrangement of parts, an example of which is described in the following specification pointed out in the appended.

This form of generating manifold I comprises'an exterior substantially large exhaust duct 1 which is provided with the usual exhaust receiving ports 3 opening directly 'into the said 'manifold and *conea shape and construction of saidmanifold.

The internal manifold 2 J is preferably formed and cast integrally with the'part 1, and is provided with connecting flanges4, or any suitable-means for V4 effecting connection with other parts. The

fold, and is arranged in thecentral portions of said exhaust manifold.- The usual formof intake manifold or duct 5 is provided with ports 6' for connecting with the intake port's-of the cylinders. A connecting tube 7 is employed to connect the generating manifold with the-intake manifold 5 and is-of internal manifold 2 may be formed with a i T taper ng deslgn SImIlRItO the exhaust manlsupply pipe 9 which furnishes the carbureter with a constant flow of coal oil or other fuel to be used. I equipped with a dash regulating means 11 An air intake valve 10 is connected with the manifold-7 or at a pointin the ducts after carburization has been effected. This air intake valveis employed for the purpose of admitting air, to 1 the vaporized mixture in quantities governed by the driver of the car engaged from the dash by the device 11, means being provided for varying of the pressure by the usual form of spring pressed intake valve thereby governing the How of the volume of air into the volatilized mixture. A steam dome of comparatively small size and comprising a cylindrical shell 12 is openly connected with the water radiating system of the engine at any convenient point thereof where such connection may be had to best obtain a small quantity of the water vapor or steam which forms around the cylinder heads during the high temperature of operation of the engine. A tube 13 is provided with a regulating .valve 14, and connects with the vapor dome 12 and leads a regulated quantity of steam from the water jacket to any point centrally located in the intake manifold 5. A small pipe or tube may be directly connected with the water jacket without employing the use of the steam dome, but same is herewith employed to furnish a ready supply of collected steamto the tube. The numeral 15 points out a portion of the water iacket or cooling system of the engine where the same may be conveniently tapped, and the connection made therefrom to the intake manifold. A. hand regulating device 16 provided with a connecting rod 17, which rod is connected through a flexible joint to the valve 14, is

conveniently accessible from the dash to the operator of the car for gaging the quantity.

of vapor admitted to the explosive mixture. The vaporization of the kerosene oil is found to be so thorough in its vaporized quality as to give, after having the proper amount of air mixed withsuch vapor gas, a blue flame of a perfect hue, indicating through actual experiments that the gas generated by this system is of a quality and nature very perfect and properly vaporized for most efficient combustion.

In carbureting systems where heat is relied upon for the generation of the fuel it is sometimes desirable to provide convenient and quick priming methods for starting the car giving the engine-its initial high working temperature prior to using the non-volatile oil as fuel. With this in view the fuel tank 18 of small capacity is placed at any convenient point on the car such as the dash where occasional filling can be had and has connection with the intake manifold of the system through a priming tube 19, which tubeis provided with a cut ofi' valve 20. The tube 19 is fixed within the intake manifold and may be provided with apertures 21 for admitting the priming oil in the intake duct.

In starting the motor equipped with this for an instant only admitting a few drops or a very small quantity of the priming oil into the intake manifold and immediately cut off. The engine will readily start upon the original mixture administered to the intake which starting of the engine emits the exhaust gases from the exhaust ports into the manifold 1 heating up the carbureting manifold 52. The suction of the motor piston sets up a certain circulation-of the fuel oil to be carbureted through the several manifold tubes, passing the said oil in contact with the hot walls of the carbureting manifold fuel instantly vaporizing it into gas, said gas being further raised in temperature as it passes through the manifold 2 and to the intake of the engine. The mixture of air and water vapor through the vaporized oil is best regulated by varying the water vapor flow and air supply to the mixture to suit the varying working conditions of the engine.

The invention is presented to include all such changes and modifications as may come within the purview of the following claims:
